1 | Did you perform the Lighting Systems Diagnostic System Check? | Go to Step 2 | |
2 | Verify that the courtesy lamps are always ON. Do the courtesy lamps operate normally? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Inspect both door ajar switch input data parameters for the body control module (BCM). Refer to Scan Tool Data List and Scan Tool Data Definitions for typical values and definitions. Was a problem found? | Go to Step 4 | Go to Step 6 |
4 | Disconnect and test the switch of the affected input circuit for proper continuity in the open and closed positions. Refer to Circuit Testing in Wiring Systems. Is continuity present? | Go to Step 5 | Go to Step 7 |
5 | Test the signal and ground circuits of the affected input circuit for a short to ground, open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 11 | Go to Step 8 |
6 | Test the courtesy lamp supply voltage circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 11 | Go to Step 8 |
7 | Inspect for poor connections at the harness connector of the affected switch. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 11 | Go to Step 9 |
8 | Inspect for poor connections at the harness connector of the BCM. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 11 | Go to Step 10 |
9 | Replace the switch in the affected circuit. Refer to Door Latch Replacement in Doors. Did you complete the replacement? | Go to Step 11 | -- |
10 |
Important: Perform the setup procedure for the BCM. Replace the BCM. Refer to Body Control Module Replacement in Body Control System. Did you complete the replacement? | Go to Step 11 | -- |
11 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3 |
